The leading Russian infrastructure holding company "Natsproektstroy" has begun testing the catenary for the Moscow-St. Petersburg high-speed railway. This was reported by the press service of the construction holding.
All elements of the catenary are made in Russia and are designed for increased loads from high-speed trains.
The CS-400 catenary is the only one in Russia capable of transmitting electricity to trains moving at speeds up to 400 km/h. For better conductivity, the cross-section of its contact wire is increased: 150 mm versus 100 mm on conventional roads.
The pilot line was built on the VNIIZhT experimental ring in Shcherbinka, where supports were installed and wires were rolled out. The reinforced supports are able to withstand high vibration loads, and the depth of their foundations is 6 meters from the surface of the earth, which is comparable to the height of a two-story house. The service life of such supports is 70 years.
The tests will last until February 2026, during which Natsproektstroy will check the structure's resistance to temperature changes and the reliability of operation in various weather conditions.
The group of companies "Key Systems and Components" (GC "KSK") will begin in 2025 the production of components for the HSR Moscow - St. Petersburg high-speed train, having signed a contract with the train developer LLC "Ural Locomotives".
